INTRODUCTION

SQL (Structured Query Language) is the most popular database language in the world. It is used widely by a variety of database systems to create queries and manipulate data. SQL is generic and compatible with the majority of database systems, which explains its widespread use and why SQL certified individuals are highly valued by businesses.

During this SQL training course, participants will be introduced to the fundamentals of SQL and will gain an insight into the essentials of relational databases. The participants will quickly acquire an understanding of vital querying language concepts and will emerge from this course as well-informed individuals who are able to implement their knowledge immediately within their own organizations.

Throughout this training course, participants will engage in tasks and exercises to ensure that they become familiar with the basic features of SQL in practical terms. On course completion, participants will be able to comfortably use SQL to select, organise, insert, delete, and review data within a database. They will also understand some advanced SQL statements and be familiar with the main functions of SQL such as conversions, SQL syntax, and dates.

Attendees will not be experts (if this is desired, see our Advanced SQL training course), but will be able to use SQL to conduct daily tasks and queries.
